        Hi all,

        
        We  (French University)
              plan to implement a storage platform (distributed

              of course) for a
              volume of 750 TB. We are interesting in CEPH ... 

            
        We wonder the
              availability of professional
              support in our project approach. Do you
            know a
              professional integrator  that could assist us
            for :
        
          
            early

                design, 
            deployment
            and probably support ?

            
        I already know 2 of them. But ...

        
        Someone told me : "there is no
              need for professional

                support, just buy the equipment, install
              it and let it
                run ceph" 

        
            -> This
                  is probably true, but
                distributed storage technologies are
                  so new to us that we
                should consider professional support in our
                  project approach (especially at
                  this point).
          
          
    It depends on your actual needs, experience with Ceph and the time
    you will be able to spend testing then maintaining the platform.

    
    Ceph could be the only component in your storage platform or you
    might need to integrate it with other components (KVM, iSCSI
    targets, NFS, ...) this can generate a lot of questions (goals for
    service availability, needs for support of these other components,
    ...).

    
    You might have to plan for later increases in storage capacity which
    might or might not have measurable impacts on performance during
    transitions depending on your initial choices of hardware and
    software configurations, is it relevant to your case?

    You may have to deploy your platform incrementally for budget
    reasons which makes the previous question automatically relevant.

    
    If I were in your place and there aren't any confidential
    information preventing you to do so, I'll describe your project in
    more details here to get a first feedback from the community on the
    challenges you might have deploying your platform. Then you'll have
    a better grasp on what you'll have to ask an integrator if you
    really need one.

    
    Best regards,

    
    Lionel Bouton
